MUSIC-LEAF TU RNER?.

SPEGFICATION forming part of Letters Patent No. 661,895, dated November13, 1900.

Application filed June 4,1900. .Serial No. 19,065. (No model.)

Zh ZZZ whom t may concern:

Be it known that I, ROBERT JESSE ROSS, a subject of the Queen of GreatBritain, residing in Bootle, in the county of Lancaster, England, (whosepost-office address is 25 Exeter road, Bootle,) have invented certainnew and useful Improvements in Apparatus for Turning Over the Leaves ofMusic, of which the following is a specification.

This invention has for its object improvements in apparatus ordevicesfor turning over the leaves of music and the like.

The apparatus comprises mainly a frame which may be in one with themusic or book rest, or it may be attached to the ledge of the ordinarymusic-rest. Above or below the book, the .leaves of which are to beturned over, an arm is pivoted to the frame, such arm normally lyingfiat against the frame on the right-hand side, but which can by simplypressing a treadle or lever be forcibly turned, so as to lie flat on theleft-hand side and by means of suitable clips to take a leaf of the bookover with it, such arm returningr on the release of the treadle or leverto its normal position ready to take over another leaf.

Referring to the accompanying drawings, Figure lis a front elevation ofthe apparatus with a book in position; Fig. 2, an enlarged underneathplan, partly in section, of a p0rtion of Fig. l; Fig. 3, a frontelevation of Fig. 2; Fig. 4C, an underneath plan of a portion of theapparatus, showing the arm turned back; Fig. 5, a View showing one ofthe clips engaging a leaf, and Fig. 6 a detail view of a brake or-retarding device hereinafter described.

In the drawings, d is part of a frame, which may be the ledge of abook-rest, or it may, in combination with the part l), be a separateframe, which can be attached to the ledge of an ordinary book-rest, suchframe carrying the apparatus or devices for turning over the leaves ofthe book.

c is a clip or catch for keeping the book in position on the rest, whichcatch may be of any suitable pattern.

CZ is the pivoted arm, which turns on a fixed axle e, mounted in theframe b, or the arm may be fixed on the axle, the latter being free toturn, andjf a spring coiled around the axle in a manner well known. Thet-endency of this spring is to keep the arm in the position shown inFig. l. The arm (Z is formed with two barrels or tubes g and Zt, inwhich slide rods Z j, actuated by springs 7.: Z. The rod (shownuppermost in Fig. 2,) which is held normally by spring Z in its extendedposition, is enlarged at its end m and forms one part of a grippingdevice to grip the clips n, and the sliding rod t', which forms theother portion, is flattened at its end 0 and is held normally by itsspring in its withdrawn position. To a projecting piece p on the end ofthe rod 'Z a cord or wire q is attached, which passes first over apulley r, thence over a second pulley s, mounted in the forked end ofthe arm (Z, both turning together on the axle e and around a thirdpulley Z to the operating treadle or lever. (Not shown.)

The rod j, sliding in the tube Zt, is provided with a piu a, to which isattached one end of a rod o, its other end being attached to a pin w, soas to be eccentric to the axis ol' the arm CZ. rPhe spring-clips n(shown best in Fig. 5) have holes fr, which fit on pins fg, fixed to theframe.

,e is a springy piece of metal projecting horizontally from l) and shownbest in Fig. 6. Its enlarged end is xed in the path of the projectingpiece p on the end of the sliding rod 'z' and is chamfered on frontside, (not at rear,) so that the projection p as it moves with the armCZ from right to left, as when turning a leaf over, pushes aside thepiece into the position shown in dotted lines; but

on its return from left to right .such projec-y tion coming against therear of the enlarged end of piece ,2' bears against it, thus retardingthe speed of the arm CZ and preventing it flying back too rapidly underthe influence of the spring f. ln order to keep the leaves down whichhave been turned over, I provide a spring-actuated arm l, which restsnormally on the leaves ofthe book, but by means of a cord or wire 2,fixed to a pulley 3 and passing around pulley @L and thence to theoperating treadle or lever, the arm lis turned out of the way while aleaf is being turned over, but returns instantly on the pressure beingtaken off the treadle. 5 is a stationary spring-clip which can turn on apivot G.

7 is a pivoted catch or support for holding the arm CZ in a raisedposition to facilitate the threading of the spring-clamps ny on the pinsY; 8, a projectingpiece carried by the arm g, to which it is secured,extending to either side thereof from beneath the free end i Y @crees ofthe same and which prevents any possibility of a spring-clamp beingtaken back again with the arm. 9 represents a leaf of the book.

The mode of action of the whole apparatus is as follows: A number ofclips n, corresponding to the number of leaves to be turned over, areplaced one above the other on the fixed pins Y on the right-hand side,and one clip is sprung onto each leaf. If there be more leaves in 'thebook than is required to be turned over, they are held down by thestationary spring-clip 5, Fig. l. The arm CZ in its normal position isheld by the spring f in the position shown in Figs. l, 2, and 3 with theenlarged end 'm of the sliding piece 'j on the top of the uppermostclip, held in this position by spring l, the arm l also bearing on thebook. New if the treadle or lever to which the cords or wires q and 2are attached be depressed, the cords or wires q and 2 will be bothoperated simultaneously, the cord q operating the arm g and rod i andthe cord 2 operating the arm l. As, however, the spring f is of greaterstrength or resistance than the spring 7:., the pulling of the cordswill first slide out the rod 1'- into engagement with the clip n., andthus, in conjunction with the sliding end piece m, gripping it, the samemovement of treadle causing the arm l to commence to move. As soon asthe rod t' has traveled as far as it will go, then the further pressingdown of the treadle necessarily turns the arm d (with the clip and aleaf attached to it) rapidly from right to left, its motion at the endof the stroke being retarded by the spi-in piece ,e and the contact ofthe projection S with the clip secured to the page. The same movementcauses the arm l to move awayquite clear of the book. At the sametiinethe rode, as it does not turn on the same center as the arm d, causesthe sliding rodj to be withdrawn, as shown in Fig. 2, the clip beingprevented from returning with the rod] by the projection S, which servesas a stop for this purpose. On releasing the treadle the parts fly backinto the former position, the rod c' sliding back/thus freeingthe clipwhich remained attached to the leaf, the arm d turning back from left toright by the pressure of its spring f, and the arm l turning over, so asto press down the leaf ofthe book. rlhe several parts, in fact, assumetheir normal positions ready to turn over another leaf, and so on untilall the clips have been used up.

I claim as my inventionl. An apparatus for turning` over leaves of inusic, comprisingapivoted spring-controlled arm or carrier located inproximity to the ledge of the 1n usic-rest, clips, one of each of whichis sprung onto a leaf ofthe music to be turned, a treadle, and means forcausing the pivoted arm orcarrier at each depression of the treadle tofirst engage with the clips and then rotate half a turn in such a manneras to turn the leaf, and means whereby the release of the treadle willinstantly disconnect the pivoted arm from the clip and enable thepivoted arm to swing back ready for a repetition of the operation,substantially as described.

2. In an apparatus for turning leaves of music, a spring-controlledpivoted arm or carrier for engaging the clips that are attached to theleaves of the music and which is sw ung over by means of a lever ortreadle, said pivoted arm or carrier comprising a sliding' rod heldnormally in its extended position in contact with the outermost clip, asecond sliding rod held normallyin its withdrawn position so as to beout of engagement with the clip, means for throwing the saine intoengagement and holding the clip in conjunction with the other rodimmediately the treadle is depressed to swing over the arm, and meansfor releasing the hold of the respective rods on the clip immediatelythe carrier has been swung over, or the force that swung it over isreleased, subsi antially as described.

In an apparatus for turning over leaves of music and the like, thecombination with a turning arm or carrier, of spring-clamps adapted toengage said arm or carrier, stationary pins on which said clamps arethreaded, the said clam ps being clipped to the leaves to be turned, anarm and a rock-shaft carrying the same, a spring for normally holdingthe shaft so that the arm will rest against the turned-over leaf, a cordconnected with the said rock-shaft for rotating the same so as to movethe arm off the said leaf when another leaf is being turned, the saidcord being also connected with the turning arm, whereby both the turningarm and the clamping-arm are operated by one cord, substantially asdescribed.

4. In a leaf-turner in combination with a pivoted arm having areturn-spring, a gripping device consisting of two rods sliding in tubesor barrels on the said arm, springs in the tubes acting against the rodsso as to keep one in its extended position normally and the other in itswithdrawn position, arod attached at one end to the upper or extendedsliding rod, its other end being pivoted to the arm so as to beeccentric to the center of oscillation of such arm, a treadle or leverconnected with the lower rod, whereby on operating the treadle or leverthe lower rod is thrust ont and after the movement ot' the arm to theopposite side both rods are withdrawn as set forth.

5. In a leaf-turner the combination of the arm with its gripping device,clamps n, stationary pins y, projecting piece p, retarding device e, arml with its pulley and spring, cords or wires 2 and q and pulleys for thepurposes described.

In witness whereof I have hereunto signed my name, this 5th day of May,1900, in the presence of two subscribing witnesses.
